So I was trying to root my Xperia Z2, starting by unlocking the bootloader. I rushed through the confirmation boxes to get the code, I entered it on fastboot... And realized I haven't made a backup. Phone restored to factory state. At least I had saved my photos on the SD card, but all the files, settings, configs and apps were gone along with my IM conversation database that I hadn't backed up for a month.

And I still haven't finished rooting that device.
